CMF by Nothing Watch 3 Pro Calling Smartwatch

Everyday health insights

Watch 3 Pro helps you stay aware of your body, day and night. From blood oxygen and stress levels to heart rate, it’s designed to support you. All your wellness insights in one place, ready when you need them.

Advanced heart rate monitoring

A new optical sensor captures more detailed light signals and finer variations in blood flow from beneath your skin. That means more accurate heart rate tracking, especially during high-intensity workouts, light skin contact and across an array of skin tones. With better signal clarity, readings are up to 7% more accurate during exercise and up to 3.6% more accurate at rest compared to previous generations.

Smarter sleep monitoring

Rest is just as important as movement. Watch 3 Pro tracks your sleep more precisely thanks to enhanced motion sensors and high-frequency heart rate sampling. It recognises short naps, detects your sleep stages more accurately, and now includes a high-precision mode for even deeper analysis. Enable it when you need the most detailed sleep tracking and wake up with a clearer picture of your rest.

Active Score

Track your weekly activity with one simple number. Active Score uses heart rate data and MET values (Metabolic Equivalent of Task) to combine activity intensity and total movement, giving you a reflection of your overall physical activity.

The score updates every day and after each session, so you can see how each effort adds up. Whether it’s walking, weight training or interval runs, it gives you a clear picture of progress. The weekly goal is 100, a simple benchmark aligned with global health standards to help keep you moving, consistently.

Essential News

Get the headlines delivered directly to your wrist. Just set your preferred topics once, from tech and health to global headlines and entertainment and receive a daily digest every morning. Stay informed while brushing your teeth or sipping your first coffee.

ChatGPT on your wrist

Assistance is always a tap away. With ChatGPT* integrated directly into Watch 3 Pro, you can ask questions, get facts and plan your day using natural-language prompts. Just lift your wrist and speak. No need to reach for your phone.

Recording transcription

Capture inspiration as it happens. The built-in voice recorder on Watch 3 Pro lets you save ideas, meeting notes or to-do reminders instantly, for up to 30 minutes at a time. Once synced with the Nothing X app, your recordings are transcribed into text so you can easily find and read them. It's a simple tool to stay sharp, and be prepared, whether you're working or just thinking out loud.

Bluetooth calling with noise reduction

Make and receive calls directly from your wrist with exceptional clarity. Watch 3 Pro features two high-performance MEMS microphones and a built-in speaker, enhanced by AI-based noise reduction trained on over 100,000 voice samples. Even in noisy outdoor environments, your voice stays front and centre. You can also sync up to 30 contacts for instant access to the people who matter.

Gesture shortcuts

No hands needed. Just a quick wrist movement, like a flip or a double shake, lets you trigger key actions instantly. Whether you're in a meeting, out on a run or cooking with both hands busy, gestures offer quiet, intuitive, hands-free control.

Quick replies and notifications

Stay connected without reaching for your phone¹⁰. Watch 3 Pro lets you send short messages directly from your wrist, using preset or personalised responses. Whether it’s a quick update on WhatsApp or a casual reply on Instagram⁶, it’s an easy way to keep conversations flowing throughout your day.

Everyday tools, always on hand

Designed to simplify daily life, Watch 3 Pro includes practical features like camera controls¹³, to-do reminders, weather updates and a world clock.

And for peace of mind, Find My Phone and Do Not Disturb modes are just a tap away.

Battery that keeps up

With optimised power efficiency and smart charging, Watch 3 Pro delivers up to 13 days of typical use⁴. Even with heavy usage, you can expect 10 days of performance. And if you choose to keep Always-On Display enabled, it still runs for up to 4.5 days without needing a top-up.

Customisable widgets and watch faces

Full screen and mini widgets let you bring what matters to the front. Whether it's workouts, sleep tracking, weather, music or reminders, you decide what shows up. You can also customise your watch face to match your style by choosing colours, layouts and data items that fit your day.
